Government announced today that the border closing has been extended again. (And it will continue till Spring is what I'm hearing.)
Also:
“Non-essential” travel includes travel that is considered tourism or recreational in nature.
The United States and Canada recognize it is critical we preserve supply chains between both countries. These supply chains ensure that food, fuel, and life-saving medicines reach people on both sides of the border. Supply chains, including trucking, will not be impacted by this new measure. Americans and Canadians also cross the land border every day to do essential work or for other urgent or essential reasons, and that travel will not be impacted.
This decision will be implemented on March 21, 2020, at which time the U.S. and Canada will temporarily restrict all non-essential travel across the U.S.-Canada land border. The measure will be in place for 30 days, at which point it will be reviewed by both parties.
That is from the announcement back in March. I called the MP's office today about a friend that now lives in Florida, but his kids are all here. Since he's not returning to live, he is really not allowed to come up, quarantine and have Christmas with his kids. But I'm sure there are ways around that if wanted.
